a
The number of recorded ECG channels and the sampling frequency depends on the configuration of your sensor. Note that not all combinations
of channels and sampling frequencies are possible.
b
The default recording time for a configuration with two ECG channels and a sampling frequency of 256Hz is max. five days but other
configurations are possible, if requested from manufacturer.
The maximum possible recording time is increased when the number of recorded ECG channels and/or the sampling frequency is decreased.
Likewise, the maximum possible recording time is de creased when the number of recorded ECG channels and/or the sampling frequency is
increased. See annex II for recording times for various configurations. Note that the recording time of your sensor might be configured to be less
than the maximum possible recording time.
Battery
The sensor is powered by an integrated battery with the following specifications:
Type:
Rechargeable lithium-ion polymer battery
Battery capacity:
Typical 350 mAh
Nominal voltage:
3.7 V
Charging voltage:
4.2 V
Weight:
7 g
Battery life:
Minimum 500 recharges
Charger:
USB 5.0 VDC, 250 mA
The battery is not replaceable. Charging of the sensor should only be performed by use of the
provided USB power adapter or a computer via the provided Micro USB cable. Use of other
charging devices may damage the device and/or the accessories.
CAUTION
Always keep the battery charged when sensor is not in use. For periods of extended storage,
fully charge the device and fully recharge once every 18 months. Not following this guideline
may reduce total battery capacity and increase wear.
